To all whom it may concern.- l. I

Be it known that FRED WELLS andMART WELLS, citizens of the United States, re'sid-Y ing at Towanda, in the county of Bradford and State of Pennsylvania, have invented certain new and useful Improvements in Split Rims, of which the following is a specification. I

The invention relates to demountable rims of the split rim type and has for its object to provide adjacent one end of the split rim a plate having notches, with which notches a dog of a pivoted member carried by the other end of the split rim cooperate, said dog being intermittently movable in the notches. Also to provide the opposite sides of the plate with notches in staggered relation to each other in which notches an instrument may be placed for intermittently forcing outwardly the end of the split rim having the pivoted member and the pivoted dog, during which movement said dog is intermittently moved in the notches of the plate. With the above and other objects in view the invention resides in the combination and arrangement of parts as hereinafter set forth, shown in the drawings, described and claimed, it being understood that changes in the precise embodiment of the invention may be made within the scope of what is claimed without departing from the spirit of the invention.

In the drawings Figure l is a side elevation of the demountable rim showing the same in expanded condition.

Fig. 2 is a detail sectional viewthrough the adjacent endsof the demountable rim, showing the ends overlapped as they are when the rim in contracted.

Fig. 3 is a detail perspective view of the adjacent ends of the rim after the rim has.

been expanded.

Referringto the drawings, the numeral 1 designates a conventional form of split ring and 2 and 3 the abutting ends thereof. Welded or otherwise secured at 4 to the end 2 of the rim is a plate 5, said plate having its end 6 slightly spaced from the end of the rim on which it is secured. Plate 5 on opporality of notches 7 and 8, the notches on each side being in stepped relation to the notches on the other side, the purpose of which Wlll presently appear. Plate 5 at a point substantially centrally thereof is provided with Specification ofiLettersiatenta, f

Pivlotitlly secured *asatYlO tothe end'3-of the it will be seen that the plate 5 is beneath the I tioned that the dog 12 will engage one of the notches 10, said dog being proportioned so that the end 3 of the rim will register with one of the notches 7 or 8, thereby allowing the insertion of a'tool in one of the notches and the end 3 to be forced in the direction of the arrow at until the dog 12 enters the adjacent notch 10, atwhichtime the tool may be removed, from one of the notches and placed in the adjacent notch which is uncovered, said operation being repeated until the ends 2 and 3 are in position to be forced into abutting engagement as shown in Figs. 1 and 3, at which time the pivoted member 11 is moved to the position-shown in Fig. 3 and the ends forced into abutting engagement in sucha manner that one side of the pivoted member will engage the upper side of the end 2 and, prevent further outward movement of said end.

From the above itwill be seen that a rim expanding device fora split'rim is provided which expanding device is simple in construction and so constructed that the rim may be easily and quickly expanded, thereby sions forming means'whereby the overlapped v ends may be-movedin opposite directions into abutting engagement with each other from an overlapped position, said means comprising a plate secured to one of the ends, the sides of said plate being provlded 'with aplurality of spaced lugs, the lugs of one side being in staggered relation to the lugs of the other side, a member pivoted to the other end of the rim, said pivoted member extending beyond the end of said end of the rim, a spring actuated dog carried by I said pivoted member, a plurality of notches in the upper face of the plate, the forward ends of which are in registration with a substantial center of the lugs of said plate 20 and with which. forward ends the spring actuated dog cooperates for holding the ends of the rim in various positions when an intermittentmovement outwardly is imparted to the end of the rim having the pivoted 25 member by inserting a tool behind the lugs carried by the plate and in engagement with the overlapped end and forcing said overlapped end outwardly.

In testimony whereof we affix our signa- 30 tures. r
